I have not had a problem receiving MMS until now. All of the sudden I get a message that I can't download a picture on Textra and when I do receive it, it is a blank black square and I can't even see it.
I have images auto-download to my Downloads folder and it shows up fine but when I tap it to open the photo, it shows a broken image.
All of the people I get MMS from are iPhone users. I finally had them send it to my on email and the image came to be over 2MB.
I have also tried default sms app, Hangouts, and Hello sms to see if it was just Textra, it's not..
APN checks out normal for AT&T, rooted, 4.2.2, I377UCUAMF3
(I also went to AT&T to see if they could do something about it but as soon as I told them I rooted they told me to basically leave... Nice)
Let me know if you need any more information to help get this solved.
